摘要
近二十多年来,随着理论地震学和计算技术的发展,理论地震图的计算技术有了飞速发展.目前已能对不同的介质模型和震源计算各种体波、面波、地球自由震荡和静态位移场.它们在研究天然地震震源过程、地球内部结构、近场强地面运动、核爆作监测以及地震勘探等领域中发挥了越来越大的作用. 目前常用的理论地震图计算方法主要包括积分变换法、离散数值方法和射线方法几大类.本文对这些方法分类进行了简单介绍,并评论了各种方法的特点和各自的适用范围.
During the last two decades, the technique of synthetic seismograms has been developed rapidly along with the developments of theoretical seismology and computer science. Today seismologists can synthesis the body waves, surface waves, free oscillations and calculate static deformation for various kind of earth models and sources. The methods of synthetic seismograms have been widely used for investigating earthquake source processes, structure of the earth's interior, strong motion seismology and seismic exploration.Various types of methods, e.g. integral tran sform method, purely numerical method and ray method, are widely used by seismologists to generate synthetic seismograms. This paper intends to give a brief review on these methods.
